Specification of Letters Patent.

Applieationled September 29, 1910. Serial No. 584,567.

To all whom it may concern:

Be it known that I, GEORGE MATGHELL, a citizen of the United States, residing at South Pasadena, in the county of Los Angeles, State of California, have invented a new and useful device to be known as a Fire, Smoke, Steam, and Air Shaft, of which the following is thespecification;

This invention relates to improvements in fines or outlets for buildings of all kinds, steam-ships and the like, and it has for its object the-provision of a non-combustible flue or duct adapted to be arranged in a building in such a manner that in the ease of tire, the smoke, flames, steam, gases and the like will be drawn into said flue 01 chimney and carried upwardly outside the building or other structure where it may be sa`fely discharged. t

The invention comprises the novel constructions, combinations and arrangements of parts hereinafter described and claimed.

Inthe drawing, Figure l'is a side elevation of a flue constructed in accordance with this invention, the said flue being shown as passing upwardly through a plurality of oors. Fig. 2 is a central vertical sectional View taken longitudinally through the upper portion of the flue. Fig. 3 is a horizontal cross sectional view through the flue or chimney taken upon the line 22 of Fig. 1.

Referrin to the drawing in which the preferred orrn of fiue embodying the invention has been shown, 1 indicates the shaft or mainv closure of the, f1ue,.2 the inlet ports or ducts, and Sthe outlet discharge opening at the top.

The flue or duct forming the subject matter of this invention is particularly useful in buildings or other similar structures or in case of steam-ships and the like where there are one or more floors or decks, when fire breaks out and threatens to damage the structures.

The flue is constructed of fire resisting material, preferably cement or reinforced concrete, and may be made rectangular, cylindrical or. any other desired shape as preferred. The main duct of the iiue 1s preferably arranged to extend from the basement or bottom compartment of the structure or building upwardly through the door 3 and the roof 4 thereof as illustrated in Figui of the drawing, the upper end of the flue being carried a-'suiiicient hei ght above the structure toprevent danger thereto', from ratented'Jan. 16,1912.

The said duct or flue l is provided preferably just below each'iioor or deck withone or more inlet openings orports 2 which lead into lthe hollow central portion of the flue.' Ait each of said openings inclined converg1ngf1oors or partial partitions are arranged, leaving a central opening 6 for the draft maintained upwardly through the flue.n These converging floors or partial partitions 5 insure vthe directing of the fiames, sinoke, steam and the like 1n an upward direction within the Hue. The upper end of the flue is usually provided with a cover or cap plate 7 of any desired shape which rests upon standards 8 extending upwardly above the upper end of the said fiue. Thus ample exit spaces as at 3 are provided at the discharge end of the flue or chimney.'

The inlet opening 2 may be provided with doors or closing means if preferred which can be arranged so as' to be supported by fusible means. In the event of a tire the heat will melt the fusible supports and permit the opening of the doors.

As is well known in cases of fires inbuild-` ings or like structures or ship, the draft occasioned by shafts, stair-cases and the like tends to draw the flames and smoke at these points. By providing a iiue having a better draft than such openings, the flames, smoke, bad fu1nes, and steam will be drawn into said flue and carried upwardly and outside of the building. By placing the openings Q just below the ioors or ceilings they are in the best position to receive and collect all of the smoke, steam and ames Oppor- :tunity is thus given the fire departments to apply fire extinguishing means in the most effective manner.

What I claim iszl. A fire and smoke tiue for buildings adapted to extend froinlthe bottom through all the fioors free from the walls thereof, and through the-top of the building, said flue having relatively large inlet apertures justy below the ceilings of each door, the said apertures extending practically' entirely around the flue sons tol employ the entire capacity of the fiue in accommodating the cscaie of smoke, gas, or the like, in case.

of ire, and inclined funnel-shaped flors arranged opposite each of said openings and.

extending abovethe plane ofthe ceilings, the inclination thereof tending to direct the smoke upwardly in the fiue.

2. A11 integral single flue fire and smoke stack for buildings,adapted to extend from practically secure a converging draftto the .extent of the capacity of the iue in accommodating the escape of smokey gases and the like the case of lire, and inclined Heers arranged entirely around the lue, so as to' -at each of saidV obeningg'the inward pro jectiou of said floors tending to facilitate the entrance of smoke and flames into the iiue at -the successive floors -without the entrance thereof being out off by the column of Inai terials already moving in said flue.
